Information × Registration Number 0119U101760, ( 0223U000870  ) R & D request Title Development of the technique of experimental evaluation of the resistance of the reactor steels at a biaxial load in the temperature range -150С ... + 350С Head Sydiachenko Viacheslav G., Registration Date 14-05-2019 Organization GS Pisarenko Institute of Strength Problems of the National Academy of Sciences of Ukraine popup.description1 In order to assess pressure vessels integrity in Ukraine, it is used normative temperature dependence of the resistance to cracking of reactor steel, constructed according to the results of tests of specimens with cracks under one-axis static load, which does not allow to assess the fracture toughness of reactor steels at different sizes biaxial load (λ = 0.5 for reactor housing and pipelines from working pressure and λ≈ 1 of the thermal stress, for example, with thermal shocks). The purpose of this project is to develop an experimental methodology for studies biaxial loading on the characteristics of crack resistance with allowance temperature popup.nrat_date 2024-12-10 Close
